[0039] Working principle of this utility model:

[0040] During installation, baffles 200 are first laid on the inner walls of both sides of the strip foundation groove 101, and then a plurality of stirrups 201 are laid in parallel in the strip foundation groove 101. The plurality of stirrups 201 are connected by a plurality of main bars 202. The stirrups 201 and the main bars 202 can be connected and fixed by welding or wire binding. Then, the support legs 300 are inserted according to the positions of the holes generated by the staggered holes between the stirrups 201 and the main bars 202, so that the bottom ends of the support legs 300 are in contact with the bottom of the strip foundation groove 101 for support. The second bolts 305 on both sides of the rotating support rod 302 will rotate and move in the first threaded holes 307 when the second bolts 305 rotate, and the moved second bolts 305 will be away from the contact with the connecting strip 304, so that The connection between the connecting strip 304 and the support rod 302 is loosened, and then the position of the support rod 302 on the connecting strip 304 can be adjusted. During the adjustment process, the second bolt 305 will be driven to slide in the adjustment hole 306, so that the two support rods 302 can face the four positioning grooves 308, and the two support rods 302 are respectively placed in the positioning grooves 308 on the two U-shaped frames 301 at the corresponding positions for positioning to prevent deviation, and then the second bolt 305 is rotated in the opposite direction and tightened. Under the action of the second bolt 305, the connecting strip 304 will be close to the support rod 302 again to prevent the support rod 302 from loosening, and the position of the support rod 302 can be adjusted according to the position of the second threaded hole 309, so that the second threaded hole 309 on the support rod 302 can be aligned with the second threaded hole 309 on the support rod 302. The second threaded holes 309 on the U-shaped frame 301 are aligned and connected, and the first bolts 303 are screwed into the two second threaded holes 309 at the corresponding positions to connect and fix the U-shaped frame 301 and the support rod 302, so that the support rod 302 can be adjusted in the horizontal or vertical position to adapt to the positions of the stirrups 201 and the main reinforcement 202. After completion, the steel pipe column flange 400 can be placed on the two support rods 302 for support. By setting a reinforcement plate 402 on the steel pipe column flange 400 and the steel pipe column 401, its stability can be improved. After placement, the first nut 404 can be taken and placed on the bottom side of the steel pipe column flange 400, and the steel pipe column screw 403 is inserted into the mounting hole 407 at the corresponding position and the first nut 4 04 is rotated and screwed on the steel pipe column screw 403, and the installation hole 407 will extend into the strip foundation groove 101. Then take the second nut 405 and screw it on the top side of the steel pipe column screw 403, so that the first nut 404 and the steel pipe column screw 403 can sandwich the steel pipe column flange 400 in the middle. Continuous rotation can make the first nut 404 contact with the bottom side of the steel pipe column flange 400, and the steel pipe column screw 403 contacts with the top side of the steel pipe column flange 400. By rotating the first nut 404 and the steel pipe column screw 403, the length of the steel pipe column screw 403 extending into the strip foundation groove 101 can be adjusted. After all the steel pipe column screws 403 are installed, concrete can be poured into the foundation layer 100 so that the concrete can cover the stirrups 201 and the support rods 302.The poured concrete layer can be reinforced by laying the baffle plate 200, the stirrups 201 and the main reinforcement 202, and the solidified concrete can fix the steel pipe column screw 403, thereby completing the installation of the steel pipe column 401.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
